CLP and EWM are aquatic invasive species that we have been performing control actions on for nearly 12 years (CLP) and 5 years (EWM) using money from a local levy administered by the Clearwater River Watershed District. The levy ensures that all lakeshore property owners are contributing to AIS control even though the MN DNR limits the treatment area to 15% of the possible treatment areas per year. Treatment along your shoreline does not increase your taxes and denying these treatment applications along your shoreline will have no effect on your taxes paid over the coming years. Note that the treatment areas are determined by surveys to identify treatment areas to provide maximum impact within the 15% limit from the DNR.  Abiding by the 15% limit ensures that the treatment does not have adverse  effects on fish and wildlife populations that we all enjoy on our lakes.

    The Euarasian Water Milfoil infestation in 2025 was unexpectedly large as there was only one area identified in 2024 requiring treatment on Marie and none on Louisa.
